Problems with Bubbles on Edge Phones

Hello everyone, I think I have looked everywhere on the forum but without any results. I have got a problem with bubles in the corners of the edge screen, most of the time it's just one corner with various size bubbles but not bigger than 2-3cm. I am using TBK-768 machine for OCA lamination, which is great for flat screens but when Im trying to laminate OCA on curved screen it leaves like a white marks on the edges or corners (i dont really know why and what is it). And after lamination i put it to LY GROUP CHINA 4in1 laminating machine (ill add screenshots below) and when it comes out there are no bubbles anywhere except for the corners.
The settings for the machine are:

Vacuum Time: 15s
Lamination Time: 13s
Outgassing Time: 5s
Debubbling Time: 600s

Could anyone help me with this? Thank you.
